Buddha told Kātyāyana: “There is a duality (dvayaṃ) that the world relies on (依), namely, existence (atthitañ[1]/astitā) and non-existence (natthitañ/nastitā), which are to be taken (取) via the touch [of cognitive faculty, object and consciousness] (觸). What is taken via the touch is [the world that relies on] either existence or non-existence. Without taking, the dependent relation between mind and object ceases itself to take [any object], to dwell [in any object] or to believe in [the reality of it-]self. [Without taking,] let it be when suffering comes; let it cease when suffering goes, and to this one holds no doubt because this is known not via the other. This is the right view(sammādiṭṭhi/samyagdṛṣṭi), and this is called the right view that is established by Buddha. Why is that? Arising (集) of the world as how it is correctly seen and understood shows the non-existence of the non-existing side of the world, while cessation (滅) of the world as how it is correctly seen and understood shows the non-existence of the existing side of the world. That is called the middle way which avoids the two sides......"
